Trees of different kinds and their uses. 
For a list of our forest trees, I shall refer you to the de- 
scriptions published by Bartram, Catesby, and Marshal—but 
{shall speak of the uses of some of them. The bark of the 
Quercus Citrinus, or yellow oak, is not only used for tanning 
leather, but also affords a very beautiful, and permanent yel- 
low. It is much used by our cloth dressers for that purpose. 
The bark of the Juglans cinerea, or butternut-walnut, is also 
used for dyeing—and affords a great variety of shades from 
deep black toa light brown. Anextract carefully prepared 
from the bark, isa valuable, and salutary physic, while the 
wood makes a very tight, and useful kind of coopers?’ ware. 
The bark, from the roots of the Cornus florida, or dogwood, 
collected in the spring, dried and pulverized, is nearly or 
quite equaito Peruvian bark, in curing intermittent fevers, or 
asa general tonic. ‘The bark of the Liriodendron tulipifera, 
or poplar, is also valuable for the same purposes, and is fay 
more pleasant to the taste. The bark of the Asculus flava, 
or buckeye, is said to be a valuable tonic medicine ; and the 
wood split into fine shreds, and macerated in water, is used 
in the manufacture of paper. The cones, or pods, of the 
Magnolia acuminata, or cucumber ‘tree, steeped in spirits, 
are used in the form ofa tincture, for the cure of rheuma- 
tism, and I believe advantageously. The wood of the wild 
cherry and black walnut, affords handsome stuff for cabinet - 
work, and from the yellow and white poplar we obtain the 
principal part of our boards and plank for building. The 
yellow pine abounds in some parts of our country, and af- 
fords excellent boards for floors or wainscoting, and I have 
reason to believe that the western part of the country was, for- 
merly, nearly or quite covered with groves of pine. The re-
